The animal, named Rupert, escaped Tuesday from a pen at Josie Hange's family home in Monee. Advertisement Wallabies, smaller cousins of kangaroos, are native to Australia and Papua New Guinea. Hange said Rupert is 2 feet high and weighs about 45 pounds. She said the marsupial is skittish and likely to flee if a stranger attempts to chase him. The Crete Police Department said in a Facebook post that a possible Rupert sighting occurred Thursday. The department urged anyone who spots the animal to report his location to authorities and not to attempt to capture him without assistance.
